It is CLIMB!!! My favorite hobby (and my passion) is go to mountain to climb big walls of rocks. I love it. When I'm climbing I focus on the rock, on the next move, on the body position. I focus on the moment and put all worry aside. In THAT moment, I feel the present, the life.
There are different style of climbing, sport climbing, bouldering, water climbing, and TRAD climbing. The last is my favorite but the most dangerous. In Trad climbing, you have to put the climbing safe gear on the rock to make it a safe climbing.
